Answer:
Scout chose not to fight Cecil Jacobs because Atticus had told her not to get involved in any fighting.
Step-by-step explanation:
Harper Lee's To Kill A Mockingbird revolves around the story of the residents of Maycomb in Alabama. Narrated by a young protagonist Jean Louis "Scout" Finch, the classic novel deals with themes of racism, family, good vs. evil, etc.
In Chapter IX of the novel, Scout revealed that Cecil Jacobs had said something offensive about their father, Atticus Finch, and his profession. Cecil had announced "Scout Finch’s daddy defended ni**ers" which infuriated Scout and make her want to punch his face. But since Atticus had already told and made her promise not to get involved in fights, Scout had to stop herself from hitting the boy.
